For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.
请参阅图1，本发明实施例中，一种感应式路径反转测量设备，所述标识设备安装在输电线路敷设路径的交通路面上；所述标识设备包括总处理器、振动传感器和报警发声器，所述振动传感器和所述报警发声器分别与所述总处理器相连；所述振动传感器采集所述标识设备周围预设区域的振动频率，并将所述振动频率发送给所述总处理器；当条件满足时，所述振动传感器确定所述多条路径中的候选路径为反转路径，所述条件包括经由所述候选路径传输的所述无线信号的能量在经由所述多条路径传输的所述无线信号的总能量中的占比大于阈值。Referring to FIG. 1, in the embodiment of the present invention, an inductive path reversal measurement device is installed, and the identification device is installed on the traffic road of the transmission line laying path; the identification device includes a general processor, a vibration sensor, and an alarm sound. The vibration sensor and the alarm sounder are respectively connected to the general processor; the vibration sensor collects the vibration frequency of a preset area around the identification device, and sends the vibration frequency to the general processor When a condition is satisfied, the vibration sensor determines that a candidate path among the multiple paths is an inversion path, and the condition includes that the energy of the wireless signal transmitted via the candidate path is not passing through the multiple paths. The proportion of the total energy of the transmitted wireless signal is greater than a threshold.
设共有T条路径，阈值为EG。经由待检查路径传输的无线信号的能量在经由T条路径传输的无线信号的总能量中的占比的条件的表达式可以表示为：Ei/ET>EG。其中，Ei为第i条待检查路径传输的无线信号的能量，ET为T条路径传输的无线信号的总能量。T为大于或等于2的正整数，i为小于或等于T的正整数。AP将待检查路径中的各条路径的Ei/ET分别与阈值EG比较，识别出能量占比大于阈值的一条待检查路径，并确定该待检查路径为LOS路径。可选地，待检查路径传输的无线信号的能量在经由T条路径传输的无线信号的总能量中的占比的条件的表达式不唯一,Suppose there are T paths in total, and the threshold is EG. The expression of the condition of the ratio of the energy of the wireless signal transmitted via the path to be checked to the total energy of the wireless signal transmitted via the T paths can be expressed as: Ei/ET>EG. Among them, Ei is the energy of the wireless signal transmitted by the i-th path to be checked, and ET is the total energy of the wireless signal transmitted by the T paths. T is a positive integer greater than or equal to 2, and i is a positive integer less than or equal to T. The AP compares the Ei/ET of each path in the paths to be checked with the threshold EG, identifies a path to be checked whose energy ratio is greater than the threshold, and determines that the path to be checked is an LOS path. Optionally, the expression of the condition of the ratio of the energy of the wireless signal transmitted by the path to be checked to the total energy of the wireless signal transmitted via the T paths is not unique,
10log10(Ei/ET)>10log10E，G，Ei/(ET-Ei)>EG/(1-EG)或10log10(Ei/(ET-Ei))>10log10(EG/(1-EG))等。10log10(Ei/ET)>10log10E, G, Ei/(ET-Ei)>EG/(1-EG) or 10log10(Ei/(ET-Ei))>10log10(EG/(1-EG)), etc.
由于计算机中所有的取值都是分立的，因此能量占比大于阈值的判断可以基于能量占比大于阈值，或该能量占比大于或等于另一值。该另一值为大于阈值的另一分立值，并且该分立值和阈值之间不存在任何其他分立值。Since all values in the computer are discrete, the determination that the energy ratio is greater than the threshold can be based on the energy ratio being greater than the threshold, or the energy ratio being greater than or equal to another value. The other value is another discrete value that is greater than the threshold value, and there is no other discrete value between the discrete value and the threshold value.
